Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)

Open Mode Design (FO-CAP), X7R Dielectric, 16 – 200 VDC

(Commercial & Automotive Grade)

Overview

KEMET’s Ceramic Open Mode capacitor in X7R dielectric

is designed to significantly minimize the probability of a low

IR or short circuit condition when forced to failure in a board

stress flex situation, thus reducing the potential for catastrophic

failure. The Open Mode capacitor may experience a drop in

capacitance; however, a short is unlikely because a crack

will not typically propagate across counter electrodes within

the device’s “active area.” Since there will not be any current

leakage associated with a typical Open Mode flex crack,

there is no localized heating and therefore little chance for a

catastrophic and potentially costly failure event.

Driven by the demand for a more robust and reliable

component, the Open Mode capacitor was designed for

critical applications where higher operating temperatures and

mechanical stress are a concern. These capacitors are widely

used in automotive circuits as well as power supplies (input and

output filters) and general electronic applications.

Concerned with flex cracks resulting from excessive tensile and

shear stresses produced during board flexure and thermal cycling?

These devices are available with KEMET's Flexible termination

technology which inhibits the transfer of board stress to the rigid

ceramic body, therefore mitigating flex cracks which can result

in low IR or short circuit failures. Although flexible termination

technology does not eliminate the potential for mechanical

damage that may propagate during extreme environmental and

handling conditions, it does provide superior flex performance

over standard termination systems. When combined with flexible

termination technology these devices offer the ultimate level of

protection against a low IR or short circuit condition. Open Mode

devices compliment KEMET's Floating Electrode (FE-CAP) and

Floating Electrode with Flexible Termination (FF-CAP) product

lines by providing a fail-safe design optimized for mid to high range

capacitance values. These devices exhibit a predictable change in

capacitance with respect to time and voltage and boast a minimal

change in capacitance with reference to ambient temperature.

Capacitance change is limited to ±15% from -55°C to +125°C.

Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)

Open Mode Design (FO-CAP), X7R Dielectric, 16 – 200 VDC (Commercial & Automotive Grade)

Applications

Typical applications include input side filtering (power plane/bus), high current (battery line) and circuits that cannot be fused to open

when short circuits occur due to flex cracks. Markets include automotive applications that are directly connected to the battery and/or

involve conversion to a 42 V system and raw power input side filtering in power conversion.

Qualification/Certification

Commercial Grade products are subject to internal qualification. Details regarding test methods and conditions are referenced in

Table 4, Performance and Reliability.

Automotive Grade products meet or exceed the requirements outlined by the Automotive Electronics Council. Details regarding test

methods and conditions are referenced in document AEC–Q200, Stress Test Qualification for Passive Components. For additional

information regarding the Automotive Electronics Council and AEC–Q200, please visit their website at www.aecouncil.com.

Environmental Compliance

Pb-Free and RoHS Compliant (excluding SnPb termination finish option).

Parameters/Characteristics

Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.

To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.

Capacitance and dissipation factor (DF) measured under the following conditions:

1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF

120 Hz ±10Hz and 0.5 ±0.1 Vrms if capacitance > 10 µF

Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known as

Automatic Level Control (ALC). The ALC feature should be switched to "ON."
